Carbohydrate: performance, tolerance and the next session

First published:
Research through: 27 February 2026
Foundational evidence connects fueling benefits with tolerance and recovery, without ranking products.
Selected historical research available by this Friday. Sources from earlier weeks are foundational context, not news from this week. Present-day revision; no exhaustive surveillance claim.
Topics: Fueling
Finding
A meta-analysis found an overall endurance-performance benefit from carbohydrate solutions compared with control, while the best dose and composition remained uncertain.
Limitations: Varied exercise tests and risk-of-bias concerns limit certainty; drinks are not evidence for every gel, brand or ultra-distance target.
Evidence level: Moderate evidence
Finding
Repeated feeding practice sometimes improved tolerance or absorption in endurance exercise studies.
Limitations: Small heterogeneous studies do not validate a product or maximal intake.
Evidence level: Moderate evidence
Finding
Carbohydrate availability during short recovery can affect subsequent endurance capacity.
Limitations: Short recovery experiments are not multi-day ultra trials.
Evidence level: Practice-informed
Study context: Narrative review. Athletes and active adults following prolonged exercise
Interpretation
Evaluate fueling in three contexts: the current effort, what your gut tolerates and recovery before another session. A pooled performance benefit is not a comparison of commercial products. The foundational papers support context, not a new intake ceiling or universal recovery recipe.
